Effective treatment of nail psoriasis with apremilast: report of two cases and review of the literature.

Nail psoriasis can cause great morbidity and a negative impact on the personal and work-related life of the patients. However, it responds more poorly to most drug therapies. Classically, the first line of treatment for nail psoriasis has been topical medication, but the new biological drugs seem to be the most effective treatment. Apremilast is another systemic oral drug that has shown a significant reduction of the severity in moderate-severe plaque psoriasis, as well as nail and scalp psoriasis. We present two cases of patients who exhibited a rapid response to treatment with apremilast.
